To all
Perhaps I need to clarify what I meant,
The pipe information is freely displayed upon another forum by Richard, therefore it has been placed into the public domain and as such I have then thought it would no longer have been seen as a secret
To this i assumed as we are all assisting each other if and when possible that when asked we would freely be happy to converse this already published knowledge.
However given the subsequent posts I also have to understand that Richard did not place this information upon this forum and as such perhaps Frits your lack of sharing when asked directly can be understood
We dont need a 3D model of Aprilias cylinder, all the relevant "secrets "are available in 2D drawings off various sources on the net.
I have applied most of them to various projects that have nothing to do with what Jan Thiel was trying to achieve.
But the ideas behind the tricks work in every case, for the same reason they worked initially.
Best example is the big radius on the transfer duct entry,where it begins at the bore edge.
There were several pics of this all over the place,and I can tell you with absolute surety, if you didnt see what was happening - and havnt got this in your cylinder,you are loosing Hp - simple.
We have 20 more little examples like this - as a wise man once said, look for the Devil ( or God ) in the details.
Ive got a thing thats unique and new.To prove it I'll have the last laugh on you.Cause instead of one head I got two.And you know two heads are better than one.
While I respect Frits position I personally feel information can be referenced and shared (if the information is made available publicly)

Anything I learn via any open forum can freely be passed on, and I would be happy to do so. But I do not always remember whether the information that I received, came to me via an open forum, a restricted forum, or verbal.
If you ask for a specific piece of information, I would have to check all open forums to see if it was already posted somewhere, before I can decide to pass it on.
See my problem?

Thanks Frits,
I surely can understand this given the so far discovered forum sites of which you appear upon, I would not have conceived your dilemma without you explaining it so, having thought about it now I wonder how this slipped past me
I am greatfull for you much valued assistance, to me personally and for all the many you have and I'm sure will continue to drive forward in the pursuit of perfection
It's limited but when setup is very repeatable ... the HP levels are right the power curve just looks funny because it is reading drum torque and HP rather than motor
Some pictures from the dyno sight, dynos for small radio controlled race cars, looks fun.
Liking the design of the dirt bike one above. Simple cradle for the drum, a beam to sit the bike on, could be easily made to dissemble and be moved. Or stored away in the corner of the shed when not in use.
Only worry would be is it solid enough to stop it moving round while you were using it.
For the record Qkkid was in my bed, not the other way round

Can anyone add something about Des Barry, the bike or both.
70hp on Std carbs from a air-cooled RD350 must have been fairly special then. (1983)
British F2 1985 1st Des Barry Yamaha 350
Wiki gives the results for the world F1 and F2.
1984 F2 9th=
1985 F1 10th & F2 12th.
1986 F2 7th,
googling i also found some mention of a spondon framed RZ500 being raced later.http://www.rzrd500.com/500phpBB2/vie...1b5f74881599a1
Oh it looks like Barry lives in the UK and is some sort of motivational speacker or such like.

I know not all the tricks that you do Wob hence the need (ok want) for 3D. all the pic i have seen are Seemingly originally from Frits files or have i missed some.

Reason: in the UK

Good weather and a good turnout for the practice day at Mt Welly.
With Kel still unable to ride Cotswold offered to chance his arm and take the Beast for a trot.
After a few small changes Cotswold looked to be getting to grips with the animal and enjoying himself and happily the Beast kept going all day, so a bit of progress in the reliability stakes.
The next step is the first round of the North Island series and Hampton.
[QUOTE=TZ350;1130431077]Good weather and a good turnout for the practice day at Mt Welly.
The 1st thing that comes to mind is the beast is fast. After riding FXRs for the past couple of years I need to learn how to pilot a 2 stroke again and struggled to get on the pipe out of some corners ( the infield and onto the straight )
Tee Zee was not sure the carburetion was correct and that may have been a factor as well, we did not play with it as a new carb is imminent and it was running well enough for a practice day.
All in all it was a good hit up with no dramas (which is how I like it)

Change down in the transition to the final corner, just using the clutch wont get you back onto the power quick enough. Slight touch of clutch coming out of the infield, you'll know if you give it too much!

Question do what does the float set up look like on a carb from a RSW. Is it a conventional hinged float set up? (Like a ballcock)
Or more like a floating post?(like Wob mentioned earlier he made for the BSL to counter the fuel surging with the rearwards mounted carbs) i can imagine all sorts of carburation issues on long left and right hand corner, so i am assuming it was a sliding post set up? Or are i worrying about stuff that doesn't actually occur?
